JOSEPH S. WOOD, OF BROOKLYN, NEW YORK.

GAS-MAoi-HNE.

SPECIFICATION forming part of Letters Patent No. 499,076, dated J une 6, 1893.

Application filed May 4, 1892. Serial No. 431,775. (No model.)

To all whom it may concern: Be it known that I, JOSEPH S. WOOD, a citizen ofthe United States, residing at Brooklyn,

in the county of Kings and State of New York,

have invented certain new and` useful Improvements in Gas-Machines; and I do hereby declare the following `to be al full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an automatic gas generating machine of that class in which a liquid hydrocarbon is vaporized by heat and the resulting vapor discharged, under pressure, ina jet, whereby the proper proportion of atmospheric air is drawn in and mixed therewith to form an illuminating-gas of the desired candle power; and more particularly the invention relates to certain improvements in the construction and arrangement of the vaporizing retort and conf-improvements in the heating burner and its connections with the retort and the regulator which connects with the gas holden-improvements in a regulating device connecting with the holder, the heating burner, and the house service pipes, whereby the flow of gas to the heating burner may be more quickly and accurately controlled, and the generation of gas, therefore,`

better controlled for correctly supplying either one burner or any desired `number of burners,-also to certain improvements in the needle-valve and its connections, which control the flow of gas from the generating retort to the holder.

The object of the invention is to simplify the construction and increase the eectiveness of automatic gas machines, and a more particular object is to improve the construction of the vaporizing retort.

Another Object of my invention is to provide for quickly and accurately controlling the flow of gas to the heating burner under the retort, so that the heat of the retort may be instantly controlled, and therefore the generation of gas controlled in exact proportion to the number of burners on the house service pipe which are lighted, and so that only the proper quantity of gas will be supplied to the burners, whether there be ten or only one 1n use. l

My regulating device is more sensitive and moves quicker than the drum of the gasholder, and by means of it and the connections between it and the heatinguburner, the holder, and the house service-pipe, I am enabled to supply gas to the house burners at a more uniform pressure and produce a perfectly steady iiame at the burner. Blowing of gas at the burners and a iiickering flame are thus avoided and a much more satisfactory light is produced.

The matter constituting my invention will be defined in the claims.

VI will now describe my improved gas machine in detail by reference to the accompanying drawings, in which- Figure l represents a sectional perspective view of the machine. Fig. 2 represents atop plan view with parts in section. Fig. 3 represents a transverse section on line w, w, Fig. 2. Fig. 3 represents a sectional detail of the air valve. Fig. 4 represents a longitudinal section on line or, Fig. 2.

My machine is mounted upon a base plate, A, provided with lugs or bosses, a, o" for connecting the post a and the oil pipe K, which serve to support the vaporizing retort B. The retort B, connects by lug or elbow b, with post, a, and by elbow 7.2, with the oil supply pipe K. Retort B is divided by partition, b, into an upper chamber, d, and a lower chamber d', and the upper chamber is provided with a transverse partition b', forming an outlet chamber d. The lower chamber d', is closed by a bottom plate b for protecting the coil C, from excessive heat from the burner. The inlet chamber d, of the retort is connected by a passage c, with the superheating coil C, which is arranged in the form of a flat coil in the chamber, d', and connects by passage c', with the outlet chamber d, which in turn connects by a short pipe d", with the ejector .or mixing chamber E. The bottom plate,b,

IOO

is also provided with an outlet throat e', and

with an air supply port, g. Air is supplied to chamber E, through an inlet box G, having a front plate, provided with a port, g, and containing a flap valve, g', arranged to close port, g. By means of this arrangementleakage of gas or vapor through the air box is prevented'. Chamber E, is connected by elbow m, to gas pipe M, which connects with the tank Q of the gas-holder.

The needle-valve F, is provided with a head slotted at f, and also with an adjustable screw, f', said slot serving for the passage of the bent end n, of the pivoted lever N. To the top of the retort there is secured a bracket 1r', slotted at its upper end in which there is pivotally connected the lever N by means of a pivotal pin,n, and the bent end, n of lever N projects from the pivotal connection up into the slotf of needle-valve F, for opening or closing said valve by the fall or rise of kthe holder when the outer end of lever N is engaged with the rod R, which connects with the holder drum.

The retort is provided with a transverse passage I-l, connecting with its inlet chamber, d, and to such passage is connected a pipe H', having a valve 7L', and connecting with the Bunsen burner I, below the jet orifice i', said passage and pipe serving to conduct oil or vapor directly from the retort to the burner when starting the machine into operation.

The Bunsen burner, I, is preferably arranged centrally below the retort and is provided with a jet orifice, c, and an air port, c', arranged in the usual manner, and at the bottom with an oil or alcohol cup, i, and a closing plug', A gas supply pipe, J, having a valve, j, connects with pipe Il', and with the burner l, supplyinggas thereto from the regulating device T, T. The oil supply pipe K, connects, in practice, with an elevated oil tank or with an air pressure oil tank, not here shown, and passes through the boss, a', and thence to the elbow 7c, which connects 'with the inlet chamber cl of the retort. The pipe K, is preferably packed with asbestus to regulate the iow of oil to the retort.

The holder is composed of a tank Q, having double walls, q, q', forming an annular space between them containing the water seal, and into which is inserted the inverted drum P. To the drum P, is secured a guide rod, R, by means of a bracket, p, and such guide rod passes loosely through the eye of the second bracket p,secured tothe outer wall of tank Q. Rod R, is provided with an enlarged slotted portion r, for receiving the end of lever N. A second guide rod R is provided on the opposite side of the holder to steady the up and down movement of drum P.

The gas holder is connected by a pipe S, with the interior of pipe S of my regulator. This regulator is composed of an outer cylinder or shell T, provided with an annular Water seal cup, t, into which is inserted the inverted movable drum T. The interior pipe S, forming part of the regulator, is provided at the top with a Valve opening s, in which there is suspended the conical valve t', which is connected by a cord or chain to the vertical rod u, which is secured to the top of drum Tand passes up through an opening in the top of the shell T,.where it is connected to a horizontal rod U. The outer end of rod U is screw-threaded and has connected to it by means of a nut u', the vertical rod U which connects at its lower end by a pivotal-pin u, with lever V, which is connected at its opposite end to valvej in gas pipe J, which controls the flow of gas from the regulator to the heating burner I.

The service pipe W, connects with the interior of the regulator and supplies the burners in the building.

A drip cock, s', preferably connects with the lower end of pipe S', for drawing off water of condensation.

The machine having been constructed and arranged las above described and shown in the drawings, the operation thereoffor generating gas is as follows: The o il tank being supplied with oil, air pressure is applied thereto, which forces oil up through pipe K to the retort. The Bunsen burner is first heated lup for starting the apparatus by burningasmall quantity of alcohol in the cup, LW; then when the burner is sufficiently heated, oil is supplied thereto by slightly opening valve h, in pipe H, leading from the retort. The oil Vapor now generated in the heated burner flows through the jet opening i', and draws air ink through the port t', and the gas is ignited. The iiame quickly heats the retort and its superheating coil C, whereby oil, which is supplied to the retort, is rapidly vaporized and the vapor forced into the ejector andy mixingchamber E, where it escapes through the orifice of the needle-valve, thereby drawing air through the air box G, and thence through ports g, into the mixing chamber. The mixture of vapor and air escapes throughthe outlet throat e', into pipe M, by which it is conducted to the holder from which gas is sup- IOO plied to the burners on the surface pipe and also to the heating burner l. As soon as the generation of gas is commencedin the retort, the lever N, is connected at its outer end to the slotted portion fr', of rod R attached to the holder, and then leverV is attached at nut u or pivotal pin u to rod U or U', which connect to the movable drum T, of the regulatplying gas to the heating burner for increasing the heat of the retort. Gas now being consumed at the house burners, it tlows from the holder through the regulator, causing the drum P to fall, thereby carrying downward lever N, and opening the needle-valve F, so that a larger volume of `as will flow from the retort to the holder. If the house burners are now turned out, the regulator will rise at once, and at alittle later period the drum P of the holder will slowly rise, but the regulator always rises and falls rst, then at a later period drumP rises and falls. By means of the instantaneous rise and fall of the regulator, the iiow of gas to the heating burner I, is instantly controlled, so that the heat is instantly increased or diminished under the retort, thereby instantly controlling the generation of gas in the retort. The regulator being much more sensitive than the drum of the holder, the generation of gas is much better controlled than heretofore and the iiow of gas to the burners is made uniform and a steady llame produced. It' the burners of the house service pipe are turned out, the regulator will rise at once, shutting off the iiow of gas to heatingr burner I, and drum P of the holder will also rise at a little later period, thereby shutting o the flow of gas from the retort through the mixing chamber and pipe M to the holder.
